Description

The slender filefish is a small filefish (family Monacanthidae) of the western Atlantic and Caribbean. The species reaches about 10 cm and has a strongly laterally compressed body with rough skin and an erectile dorsal spine that can be locked upright. Its colour is variable and mottled, giving excellent camouflage. It lives over sandy and rocky bottoms and often drifts camouflaged among gorgonians, where it feeds on algae and small invertebrates. The species is harmless to humans and of no fishery value.
